我们认为无密钥认证的点对点通信中存在的近视对手。特别是，对手可以访问传输的非因果噪声版本，并可以使用此知识来选择信道状态;如果接收器解码为正确的消息或正确检测到对抗性干扰，则接收器是成功的。我们表明，根据合法的接收器和对手的通道之间的关系，认证能力是零或以上的无对手的能力有界。为此，我们引入了一种新的信道属性，称为$U$ -overwritability，它允许对手，使其虚假的消息出现合法的。我们推测，如果容量是非零的，它实际上是等于无对手的能力，并表明，这是一个特定的二元模型。
We consider keyless authentication for point-to-point communication in the presence of a myopic adversary. In particular, the adversary has access to a non-causal noisy version of the transmission and may use this knowledge to choose a channel state; the receiver is successful if it either decodes to the correct message or correctly detects adversarial interference. We show that, depending on the relationship between the channels to the legitimate receiver and the adversary, the authentication capacity is either zero or bounded above by the no-adversary capacity. To this end we introduce a novel channel property, termed $U$ -overwritability, which allows the adversary to make its false message appear legitimate. We conjecture that if the capacity is nonzero, it is in fact equal to the no-adversary capacity, and show that this is true for a particular binary model.
